get_v2_userstream_by_id

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, and the description fails to disclose any behavioral traits such as permissions, rate limits, return format, or whether the operation is read-only. It only restates the purpose.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is relatively concise, consisting of two sentences. However, the first sentence is somewhat redundant and could be integrated into the second for better flow.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one parameter and no output schema, the description provides basic purpose and usage hint. It lacks detail on what 'userstream' is or what the output contains, which is acceptable but minimal.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description adds minimal meaning beyond the parameter name. It mentions 'by id' but does not clarify the format or constraints of the ID parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves userstream info by ID. It distinguishes from sibling 'get_v2_userstream_by_username' by referencing the ID endpoint. The first sentence is a bit ambiguous but the second sentence clarifies the purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives a hint about using this endpoint when speed is crucial, implying the ID-based variant is faster than the username variant. However, it does not explicitly state when to use versus other userstream tools or provide alternative scenarios.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
